To all w/tom it may concern:

Be it known that I, CHARLES XV. HAMILL, a citizen of the United States,residing at Baltimore, in the State of Maryland,'have invented certainnew and useful Improvements in WVheels for Advertising, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to a means of advertising; and it consists in theconstruction and arrangement of awheel and other features for thispurpose, substantially as set forth hereinafter, referring to theaccompanying drawings, in which- Figure l is an elevation, and Fig. 2 acrosssection, of apparatus.

The base A is made of sufficient weight to hold the apparatus firmly inplace, and bears a standard, B, which bears a horizontal journal, C, ata suitable elevation.

The journal 0 bears the wheel D, mounted on it so as to turn freely, anda fixed arm E, arranged to project over the face of the wheel, so as toact as a stationary index thereon, while the wheel is adapted to turn.

cate the journal, and a short sleeve, II, ar-

V ranged to slide over the hole to close it neatly.

The wheel has around it on its face, near the margin, a series of pins,I, at intervals in a circle, and aseries of numerals, O, in theinterspaces between the pins. The numerals are arranged odd and evenalternately, but in an irregular manner, as shown, so that large andsmall and intermediate numbers will follow each other in any desired oraveraged manner. Words-as answers to questions-are arranged in the sameway. The end of the index-arm E bears an elastic extension, K, arrangedto touch the piris I as the wheel is turned, so as to produce a slightfriction, and so as to project slightly between two pins when the wheelstops, to prevent displacement, and to in dicate a number markedthereat.

The wheel-hub F has an oil-hole, G, through which to lubri- The wheelbears projecting knobs L, by 5 which it may be turned. The face of thewheel bears one or more advertisements, M, well displayed, upon itsfixed part, and has one or more receptacles, N, with glass cover and asupporting-back,with a slotway at one edge, by which a 'card is heldbearing printed, painted, or written announcements, prices, oradvertisements, in connection withthose on-the fixed part or not, whichcan be changed from time to time by withdrawing the card and insertinganother.

The wheel can be used to determine numbers by accidental indications foramusement, and thus draw attention to the advertisements on its face.

The construction and arrangement of several of the parts may be varied.

I claim- 1. In a wheel, D, for advertising, the combination, withtheseries of pins I on its face surface, near the margin, having a seriesof numbers, 0, in the inters'paces between the pins, of the fixedindex-arm E, projecting over the face of the wheel, and having theelastic extension K, adapted to touch the pins when p the wheel isturned, as shown, and for the purpose set forth.

In a wheel, D, for advertising, the combination, with the series ofpins I on its face surface, near the margin, having a series of numbers,0, in the interspaces between the pins, of the fixed index-arm E,projecting over the face of the wheel, and having the elastic extensionK, adapted to touch the pins when the wheel is turned, and theglass-covered receptacle N, for holding interchangeableadvertising-cards, as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
